ASH-Hoist EPECIFICATIQN forming part of Letters Igatent No.289,159,`dated November 27, 1883.

I Application filed August ld, 1853 i l (No medal.)

To all whom, it nur/y concern.

Be it known that I, JOHN D. SPREoKnLs, of the city and county of SanFrancisco, and State of California, have invented au Improvement inAsh-Hoists; and I hereby declare the following to be a full, clear, andexact description thereof.

Hy invention relates to van apparatus which is especially useful forhoisting ashes from the fire-rooms of vessels and discharging themoverboard; and it consists, mainly, of a receiver for the material atthe bottom, aline of carrying-buckets with a suitable drivinginechanism, by which the buckets are caused to pass through the receiverto load themselves and pass thence to the deck above, a receivingchuteor disch arge-pipe leading out through the side of the vessel, and ameans for keeping it clear and preventing choking, together with certaindetails of construct-ion, all of which will be more fully explained byreference to the accompanying drawings, in which- Figure l is aperspective view of my apparatus. Fig. 2 is a vertical section of thesame. A. is a receiver, which is fixed in the door or hearth of thelire-room, or in any convenient place, so that when the ashes are to bedischarged [which is usually about once in six hours) they may be easilyraked into the receiver. Its sides may be vertical and sufficientlyseparat-ed to allow the buckets to pass between them. The bottom isrounded or curved, and a roller or pulley, B, is journaled to turnbetween the sides of the receiver, so that the buckets C (which arepreferably secured to a leather belt, D, to lessen the noise of working)may-be carried down by the belt and dip into the receiver, so that asthey rise upon the other side they will load themselves. The belt Dextends around a roller or drum, E, upon the upper deck, at any suitableor convenient point, and both parts of itare inclosed by a casing, F. Atthe top the upper drum-shaft extends out, and has a gear-wheel, G, keyedto it, which is engaged by a pinion, H, upon the engine-shaft I. Theshafts, gears, and the engine J, by which they are driven, are allmounted upon a frame, Ii, properly secured to thevessel. A dischargepipe or chute,

5o Il, extends from the upper deck downward,

and is curved outward, so as to discharge through the side of thevessel, and its upper end has a hood, M, extending upward and curvingpartially over the upper bucket-roller, so as to insure the discharge ofthe contents of the buckets into the chute without scattering. The chuteextends down through the second deck in a nearly-vertical position, andbelow this deck it curves outward, so as to assume a more nearlyhorizontal position and pass out through the side of t-he vessel, thusobstructing the interior space to the least extent. As the material isapt to clog when discharged through this chute, an opening or passage,N, is made into it, entering, preferably, about in line with thedirection of the lower portion, and a water-pipe connects with it with avalve, O, through which a body of water from the pump may'be dischargedthrough the pipe and forcibly clear it or prevent any lodgment of mate`rial within it. l

P isv a gate or valve fitted into the dischargechute near its outer end,and serving to close it when not in use, and thus prevent any ingress ofwater from the motion of the vessel or the action of the sea. This valveswings in a chamber of somewhat larger diameter than the rest of thepipe, so that when open it is out of the way and leaves a clear passage.Its shaft has a 1ever-ar1n with a connecting-rod and hand-lever, bywhich it may be opened and closed, and a curved link or rack withsetscrew or pawl to hold it open or closed at will. At a point above thedeck Q where the donkey-engines are usually placed I make a door, It, inthe side of the chute Il, and a plate, S, is fitted into the chute, sothat when in place it extends upward and backward from the lower edge ofthe door-opening at an incline.

`This device is used whenever it is desired to hoist coal from therefroom bunkers for the use of the donkeyengines, and the coal, beingtaken from the receiver A, is carried up by the buckets and dischargedinto the chute, flowing down to the incline-plate S, which directs itoutward through the door-opening upon the deck. When ashes are to behoisted, this plate is removed and the door closed. The ashes are rstwet down, so as to cool them, and also prevent their injuring theelevator-belt, after which they are raked into the receiver, and thebuckets, being in motion, will IOO scoop them 'up and carry them to thetop,where they discharge them into the chute, through which they escapeoverboard, as before described.

. Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, isv l. A device for hoisting and dischargingashes, adapted to be carried by a vessel, and consisting of a receiverplaced near the furnace, a chain of buckets, and a discharge-chute,connected substantially as described.

2. The discharge pipe or chute L, in combination with the water-pipe orflushing-passage opening into it, substantially as herein described.
